Embodiment 1

[0036] Add 35% epoxiconazole, 15% Jinggangmycin A, 6% sodium dibutylnaphthalene sulfonate formaldehyde condensate, 4% fatty alcohol polyoxyethylene ether and 40% deionized water to the sand mill respectively In the cylinder, after stirring evenly, pre-disperse with a high-shear machine, then transfer to a sand mill for sand grinding, add sanding medium zirconia beads, and start sanding so that 98% of the particle size is below 3 μm; stop sanding after 4 hours Grind, filter, and remove the zirconia beads to obtain a bactericidal composition suspension containing epoxiconazole and Jinggangmycin A.

Embodiment 2

[0038] 12% epoxiconazole, 18% Jinggangmycin A, 9% sodium lignosulfonate, 6% alkylphenol polyoxyethylene ether formaldehyde condensate, and 55% white carbon black were respectively prepared by premixing, Coarse crushing, re-mixing, and crushing with a jet mill. The crushed material is then added to the conical mixer. The mixed material with a fineness of 99% can pass through a 325-mesh standard sieve to obtain epoxiconazole and Wettable powder of the fungicidal composition of Jinggangmycin A.

Embodiment 3

[0040] Add 15% epoxiconazole, 25% Jinggangmycin A, 7% sodium naphthalenesulfonate formaldehyde condensate, 3% sorbitan fatty acid ester and 50% deionized water into the sand mill cylinder respectively by weight percentage, stir After uniformity, pre-disperse with a high-shear machine, then transfer to a sand mill for sand grinding, add sanding medium zirconia beads, and start sanding, so that 98% of the particle size is below 3 μm; stop sanding after 4 hours, and filter , to remove the zirconia beads, that is, to prepare a bactericidal composition suspension containing epoxiconazole and Jinggangmycin A.

Abstract

The invention discloses a bactericidal composition containing epoxiconazole and validamycin A and a preparation method thereof, wherein epoxiconazole and validamycin A are used as main components and then assisted with an auxiliary agent and deionized water to form a suspending agent, or form a wettable powder together with the auxiliary agent and a carrier. The epoxiconazole and the validamycin A are compounded, and a higher synergistic action can be generated, thereby the disease control range is enlarged, the generation of drug resistance is delayed, the drug effect is markedly improved, the burden on peasants is lightened, and agricultural safe production and ecological environments are also ensured. The bactericidal composition is applied to the field of agricultural plant chemical protection and has excellent and highly efficient protecting and treating actions for the pathogen harms of fruit trees, vegetables, wheat, rice and the like.

Description

technical field [0001] The invention relates to a bactericidal composition containing epoxiconazole and Jinggangmycin A and a preparation method thereof. Background technique [0002] Epoxiconazole: chemical name: (2RS, 3SR)-1-[3-(2-chlorophenyl)-2,3-epoxy-2-(4-fluorophenyl)propyl]-1H-1 , 2,4-triazole. The original drug is a white crystal, which is a sterol demethylation inhibitor. Epoxiconazole is a systemic triazole fungicide. It has a strong affinity for a fungal enzyme (14-dencthylase), and can inhibit pathogenic fungi more effectively than currently known fungicides. Epoxiconazole can increase the activity of vantinase in crops, leading to the contraction of fungal haustoria and inhibiting the invasion of pathogens. This is the unique characteristic of epoxiconazole among all triazole products. Epoxiconazole can be used as a high-efficiency fungicide for seed treatment or surface spraying of important economic crops. It can prevent and control a series of cereal crop...
